I am trying to install an additional application to Liberkey but get a Firefox popup window (title: Launch Application) saying that "This link needs to be opened with an application. Send to:" There is then a box in the window allowing one to choose an application. I tried LkInst.exe, but this didn't work. I've also found this to happen with more than one new application.

The problem didn't occur when I've previously added applications. Firefox version is 3.6.15.

What can I do to solve this problem?

Hello Ariel the Lion.

Does your LiberKey (LiberKeyMenu) is running when you try to add an application ?
